Popular messaging platform Telegram has been hit with a 200Gbps distributed denial of service (DDoS) attack.

The Tsunami TCP SYN flood kicked off on Friday and hurt users in Asia, Australia, and Oceania, knocking out the service for some five percent of the company's 60 million active users it has gained in 18 months.

It is a new form of DDoS attack discovered October by Radware security folk who say it is different from regular SYN floods in that it transmits large 100 byte packet sizes about double the regular 40 to 60 byte size.
